Yes you do.
First get sliver wing and explore the whirl islands. Lugia will be deep inside the island.
To the right of the town, there is a small hill will an old man standing on it. Talk to him and he will give to the Rainbow wing for Soulsilver, or the Silver wing for Heartgold.
go to pewter city and there is an old dude standing over to the right on one of those little hill thingys talk to him and he gives u a rainbow wing.
you must go to pewter city to get the rainbow wing then go to the top of tin tower.
in pewter city (i think, its definitely in kanto) there is an old man. talk to him and I cant remember if you have to answer a question but he will tell you about the olden days then give you a silver wing. hope that help :)
You can meet a level 70 Ho-oh at the top of the Bell Tower Once you have obtained a Rainbow Wing. To get a Rainbow Wing you talk to the man on the raised pavement in Pewter City.
If u mean lugia its in the whril isles but u need the tidal bell from the kimono girls and the sliver wing to get to lugia
you have to get the silver wing from the director of the goldenrod radio station then beat kimono girls to get tidal bell and then go with them to the whirl islands and lugia is there
you get the silver wing after you defeat team rocket went they take over the golden rod radio tower prof. elm will call you about the broadcasts from the radio tower after you beat the gym in mahogany town
